Thermo-optical interactions in a dye-microcavity photon Bose-Einstein condensate [PDF]
New Journal of Physics, 2017 Superfluidity and Bose-Einstein condensation are usually considered as two closely related phenomena. Indeed, in most macroscopic quantum systems, like liquid helium, ultracold atomic Bose gases, and exciton-polaritons, condensation and superfluidity ...

Photon-Photon Interactions in Dynamically Coupled Cavities
Physical Review A, 2019 We study theoretically the interaction between two photons in a nonlinear cavity. The photons are loaded into the cavity via a method we propose here, in which the input/output coupling of the cavity is effectively controlled via a tunable coupling to a ...

Photon-photon interactions in Rydberg-atom arrays [PDF]
Quantum, 2022 We investigate the interaction of weak light fields with two-dimensional lattices of atoms with high lying atomic Rydberg states. This system features different interactions that act on disparate length scales, from zero-range defect scattering of atomic excitations and finite-range dipole exchange processes to long-range Rydberg-state interactions ...

Measuring photon-photon interactions via photon detection [PDF]
Physical Review A, 2010 The strong non-linearity plays a significant role in physics, particularly, in designing novel quantum sources of light and matter as well as in quantum chemistry or quantum biology.

Jet Production in Photon-Photon Interactions [PDF]
, 1996 The inclusive one- and two-jet cross-sections are measured in collisions of quasi-real photons at e+e- centre-of-mass energies of 130 and 136 GeV using the OPAL detector at LEP. Jets are reconstructed with a cone jet finding algorithm.

Storing single photons emitted by a quantum memory on a highly excited Rydberg state [PDF]
Nature Communications, 2016 Strong interaction between two single photons is a long standing and important goal in quantum photonics. This would enable a new regime of nonlinear optics and unlock several applications in quantum information science, including photonic quantum gates ...

A photon–photon quantum gate based on Rydberg interactions [PDF]
Nature Physics, 2018 The interaction between Rydberg states of neutral atoms is strong and long-range, making it appealing to put it to use in the context of quantum technologies. Recently, first applications of this idea have been reported in the fields of quantum computation and quantum simulation. Furthermore, electromagnetically induced transparency allows to map these

Photon–Photon Interactions and the Opacity of the Universe in Gamma Rays
Universe, 2021 We discuss the topic of the transparency of the Universe in gamma rays due to extragalactic background light, and its cosmological and physical implications.

Fully - heavy tetraquark production by γγ interactions in hadronic collisions at the LHC
Physics Letters B, 2021 We investigate the production of the fully - heavy tetraquark states T4Q in the γγ interactions present in proton-proton, proton-nucleus and nucleus-nucleus collisions at the CERN Large Hadron Collider (LHC).
